Secure load and pressure measurement according to SIL3 and Performance Level e .

On numerous theatrical stages in the world as well as in the industrial force measurement technique, the load measurement with overload protection by Müller Industrie-Elektronik already provides a maximum in security for many years.

With the long-standing know-how in force measuring technology for the highest security requirements, Müller Industrie-Elektronik currently offers the new Safety Measuring Module SMM  which is accredited corresponding to the high demands of the safety standard SIL3 according to EN 61508/62061 as well as meeting Performance Level e, category 3 according to EN ISO 13849-1.

Combined with a safe evaluation unit  (µC | PLC | PC) the new Safety Measuring Module SMM is a redundant, SIL3-certified measurement system for secure load, force, pressure and differential pressure measurements with SIL3-compliant evaluation.

With the SIL3 and Performance-Level e certification there are many application areas for the Safety Measuring Module SMM in all sectors where safety-related sensor signals in bridge circuit are required, such as: Marine engineering and port logistics, event and stage technology, crane and hoisting technology, agricutural and construction machinery, commercial and special vehicle construction, lift tables and platforms, heating systems, ship lock facilities, tire production, process steam control or turbine monitoring.

The product portfolio of the SIL3 certified safety electronics for strain gauge bridge signals includes the three product types:
  • Modular universal load cell MULC
  • Robust field case SMM-HD
  • DIN-Rail case SMM-DR
